The present invention relates to a whip roll device for a loom and moreparticularly to a whip roll mounting or supporting structure.

In a conventional loom, there is provided a whip roll over which thewarp passes from its beam to the harness. The whip roll serves as aguide to direct the warp sheet substantially horizontally from the warpbeam towards the harness and to tension said warp sheet. The whip rollmay be correlated with the let-off motion or may simply serve as a warpguiding and tensioning device.

One object of the present invention is to provide a new and improvedwhip roll supporting structure, which afiords resilient, or fixed,mounting of the whip roll in operative position, which is easilyadjustable to permit adjustments in the position of the whip roll withrespect to the cloth fell in accordance with the different weavingconditions desired and which is self-aligning to assure proper alignmentof the whip roll in spite of inaccuracies and to permit the positions ofthe ends of the whip roll to be adjusted separately.

Various other objects will be apparent from the following particulardescription and from an inspection of the accompanying drawings, in

- which:

Fig. 1 is a rear fragmentary view of the loom showing the whip rolldevice and its supporting structure embodying the present invention;

Fig. 2 is a side elevation of the supporting structure for one end ofthe whip roll; and

Fig. 3 is a section of the whip roll supporting structure takenapproximately along the lines 3.3 of Fig. 2.

The drawings show the improved whip roll device and part of a loom towhich the same may be applied. The loom is shown comprising a rightloomside I and a left loomside ll interconnected by cross-members suchas girts and each comprising an inner web I2 and an outer web l3suitably cross-braced. The loomsides mount bearings M for rotatablysupporting a warp beam l5 containing the warp supply from which the warpsheet is taken. The warp sheet extends upwardly and forwardly about awhip roll it and then forwardly towards the front of the loom into thefield of operation of the shedding mechanism.

The whip roll l6 of the present invention is not of the type which iscorrelated with the op eration of the let-ofi motion as in the case of aBartlett let-off motion, but desirably is of the type which has noconnection with the let-ofi motion and serves merely as a Warp guidingand tensioning device.

5 Claims. (Cl. 139-114) In the specific form of the invention shown, thewhi roll l6 comprises a, steel tube 20 closed at its ends by plugs 2|press-fitted or otherwise secured therein and each having an axial holeinto which is fitted a gudgeon or journal 22. These gudgeons are securedto respective plugs 2| by pinning or the like and are journalled in thebearings 23 of whip roll supports 24 at the opposite ends of the whiproll it.

Each of the whip roll supports 24 comprises a rod or shank 25 having atone end a head in the form of an eye defining the bearing 23. Thisbearing comprises a bearing ball 26 retained in a suitable socket orrace structure 21 for free universal movement therein and having acircular hole 28 through the center to receive the gudgeons or journals22 with a press-fit. The udgeons 22 thereby rotate with the respectivebearing balls 26, which are free to move universally in the socket orrace structures 21.

Each of the whi roll support rods 25 passes through a, sleeve 35 with afree snug slide fit and is formed near one end with an axially facingshoulder 36 at the base of the bearing 23, for the purpose to bedescribed, and at its other end projects beyond the corresponding end ofsaid sleeve and is threaded to receive a limiting nut 31 and a lockingnut 38. A coil spring 40 encircles the rod 25 beyond the sleeve 35 andis seated at one end against said sleeve and bears at the other endagainst the shoulder 36 to urge the rod axially in one direction alongsaid sleeve and against the limiting action of the nut 3']. The nut 31can also be set tight against sleeve 35 thereby eliminating the actionof the spring 40 and providing a solid support for the whip roll [6. Atube 4| embracing one end of the sleeve 35 and secured thereto, as forexample by welding, houses the coil spring 40 and limits movement of thewhip roll support rod 25 in an opposite direction. I

The sleeve 35 is supported for angular and lengthwise adjustments. Tothat end, there is secured to the outer face of each inner loomside web12 a bracket 45 serving as a swivel support for a clamp 46 embracing thecorresponding sleeve 35. The bracket 45, as shown, is connected to theloomside web,l2 by cap screws 4'! of the socket type and has a circularrecess 48 on the side thereof nearest the loomside web l2 and a circularhole 50 of smaller diameter extending from said recess. The clamp 46 hasa circular flange 5| at one endextending inthe bracket recess 48 with aswivel or-rotative fit, a cylindrical section 52 of reduced diameterpassing through the bracket hole 50 with a bearing or swivel fit, and asplit clamping part 53 embracing the sleeve 35.

The sections of the clamp 46 on opposite sides of its split arereleasably drawn towards each other and about the sleeve 35 by means ofscrews 54 shown of the cap socket type.

The bracket 55 is of the split clamping type and has the sections onopposite sides of its split releasably drawn towards each other andabout the clamp flange i and the cylindrical clamp section 52 by a bolt56 shown of the socketed head type.

To afford visible indications of the adjusted angular position of thewhip roll supports 2 the exposed face of each bracket 45 has a series ofindicia 60 arranged around the edge of its hole 50 along a quadrant arcand the exposed face of the clamp section 52 has a radial pointer Blmarked thereon for indicative cooperation with. said indicia. Theindicia 6n and the pointer 6| are desirably so arranged, that when therod 25 and embracing sleeve 35 extend vertically, said pointer will bedirected to one end of the indicia scale and when said rod and sleeveextend horizontally, said pointer will be directed to the other end ofthe indicia scale. The whip roll support 24 will thereby have a range ofadjustment. of 90 from vertical to horizontal.

To aiTord visible indications of the adjusted lengthwise position of thewhip roll supports it, the sleeve 35 has arranged therealong a series ofindicia 62 indicativel-y cooperating with the ad joining edge of thesplit clamping part 53 of the clamp 46.

For adjusting the postion of the whip roll !6 the clamping bolt 56 foreach support 24 is loosened to permit the clamp 46 to be rotated to thedesired angular extent and the whip roll it to be located thereby in theapproximate desired. position with respect to the cloth fell. Theelevation of the whip roll 16 can be adjusted approximately by looseningthe studs or screws 54 and. moving the sleeve 35 lengthwise in the clamp45. By properly maneuvering the two adjusting devices .for angular andlengthwise movements of the whip roll supports 24, the bearings 23 canbe accurately located in the desired positions, in accordance with therequired weaving conditions. The bolt 56 and screws 54 can then betightened in the adjusted position of the whip roll supports 24.

The bearing .23 in .each whip roll support 2 being of the universaltype, said supports can be adjusted one at a time. Furthermore, thishearing feature permits proper self-alignment of the bearings 23, tocompensate for inaccuracies in adjustments or in construction.

While the invention has been described with particular reference .to aspecific embodiment, it is to be understood that it is not to be limitedthereto but is to be construed broadly and restricted solely by thescope of the appended claims.
